累积分布函数显示了数据小于或等于某个值的概率。我们可以使用Matplotlib来绘制CDF。 # 计算CDF data_sorted = np.sort(data) cdf = np.arange(1, len(data_sorted) + 1) / len(data_sorted) 绘制CDF plt.plot(data_sorted, cdf) 添加标题和标签 plt.title('Cumulative Distribution Function') plt.xlabel(...
orientation:可选,指定直方图的方向,包括垂直(v)和水平(h)。 cumulative:可选,指定是否绘制累积分布函数(cumulative distribution function,CDF)。 histfunc:可选,指定直方图的统计方式,包括计数(count)、求和(sum)、平均数(avg)、中位数(median)、最大值(max)和最小值(min)。 barmode:可选,指定多组数据的绘制...
Seaborn简介 Seaborn是一个基于Python的数据可视化库,它建立在Matplotlib库之上,提供了更高级的接口用于绘制统计图形。Seaborn的目标是使复杂的数据可视化工作变得更加简单和直观,同时生成具有吸引力、信息丰富的图形。它特别适合于探索性和解释性数据分析任务。下面是一些Seaborn的关键特性和功能: 数据集的高级接口:Seaborn设...

This leads to a recalibrated probability distribution that, however, has no analytical representation but is given by certain points defining a CDF distribution. Non-parametric calibration methods are netcal.regression.IsotonicRegression and netcal.regression.GPBeta. In contrast, parametric calibration ...
